About formats

AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.
Initial release: February 8, 2019
DBK is a file extension associated with DocBook, a semantic markup language for technical documentation defined in XML (and originally SGML). DocBook was created around 1991 by HaL Computer Systems and O'Reilly & Associates, later maintained by the OASIS DocBook Technical Committee. The vocabulary provides over 400 element types designed specifically for books, articles, reference pages, and technical manuals — including structural elements (book, chapter, section, appendix), block elements (para, programlisting, table, figure), and inline elements (emphasis, filename, command, classname). Authors write content focusing on meaning rather than appearance, and separate stylesheets transform the DocBook source into output formats like HTML, PDF, EPUB, and man pages. One advantage is strict separation of content and presentation — a single DocBook source document can generate a printed book, a website, an ebook, and Unix man pages through different transformation pipelines, without any content duplication. The rich semantic vocabulary is another strength: because elements like <command>, <filename>, and <errorcode> carry precise meaning, toolchains can index, cross-reference, and validate technical content in ways that generic markup cannot. DocBook has been adopted by major open-source projects including the Linux kernel documentation, GNOME, KDE, and FreeBSD for their official documentation, and it remains the standard for single-source technical publishing.

DocBook XML format incorporates your image into technical documentation — the standard for structured authoring of manuals and tech guides.

Which apps support DBK files?

You can open DBK files with XMLmind, oXygen XML Editor, LibreOffice. Free alternatives are available for every platform.

Will my AVIF image look the same as DBK?

The visual appearance is preserved as closely as the DBK format allows. Any differences are typically imperceptible to the human eye in normal viewing.

Does this work on mobile devices?

Yes — the AVIF to DBK converter works in any mobile browser on iOS and Android. No app installation is needed — just open convertio.tools and upload your file.

How long does AVIF to DBK conversion take?

Most conversions complete within seconds. Processing time depends on file size and server load, but the entire workflow typically finishes in under a minute.
